Hello mam, thanks for trusting health care magic.
this is very common to have irregular periods
for a couple of months after taking progesterone
for postponement of periods so nothing to worry as yet but definately keep using some regular contraception
in case you are not desirous of pregnancy
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
